I’ve tried to make this as intuitive as possible, but just in case you can’t read my mind, here’s how it goes:

• Tap the bead that you want to move. The bottom 5 beads each hold a value of one. The top 2 beads each hold a value of 5. These values are multiplied by 10 per column to the left of the first. Once you have a value greater than 10 in a column, the abacus automatically rounds the value to the column to the left.
• If you would like to account for decimals, use the page-up/down hard button. This moves the decimal bar.
• You can copy the value into the clipboard from the “Ftns” menu or c-shortcut.
• You can change the color of the bead or bars from the “Prefs” menu.

The Internet has lots of great resources describing how to use an abacus. A couple of the sites which I found helpful are…

• The Abacus: The Art of Calculating with Beads
• The Abacus Handbook
